IMPROVEMENT IN NAIL-DISTRIBUTERS.

Specification forming part of Letters Patent No. 144,407, dated November11, 18735 application filed September 17, 1873.

To all whom it may concern Be it known that I, ALEXANDER MORRISON,

l of the city of Harrisburg, county of Dauphin and Sta-te ofPennsylvania, have invented an Improved Spike-Rejecter forSpikeMachines, of which the following is a full, clear, and eX- aetdescription, reference being had to the drawings making a part of thisspecification.

The object of my invention is to provide any ordinary spike-formingmachine with a simple and efficient apparatus by which, at the option ofthe operator, a defective spike (also the initial and final cut oftheplate from which spikes are made) may be rejected by an articulatedupper division of the chute, momentarily directed to convey the refuseto a receiver under the rear end of the machine, while the normallyself-restored ch'ute conveys the accepted work to a separate receiverunder the fore end ofthe machine. My invention, therefore, consists,rst, in an articulated chute, composed of a stationary chute, and anoscillating chute at the upper end of the stationary chute, these partsbeing made to coalesce to form but one chute by the automatic action ofthe trip mechanism 5 seeond, the trip mechanism, composed of connecting-rod, joining the oscillating chute and the trip-lever, a coiledspring set to retract the said lever, and a plunger connected with thelever, by which it is made accessible either by the foot or the hand ofthe operator when seated or standing; third, a shield beneath themachine-bench, next the exit-opening therein, in connection with theoscillating chute when tilted to reject work, and in connection with theframes by which the apparatus is mounted.

In the accompanying drawings, making a part of this specification,Figure l is a side elevation of myiniproved spike-rejecter, thespikemachine bench being shown invertical section, and the apparatus isshown adjusted to reject work. Fig. 2 is a side elevation of the Samewith the chute directed to accept work.

I mount my apparatus connectedly on two uprights, W, which are joined attop and bottom box form, and are of proper height to reach from the door011 which the machine stands to the under side of the machinebench B,which is provided with the usual exit-passage A, to let work G passdownward from the dies, (not shown.) A vertical shield, T, on the frontside of said opening, curbs condemned work from jumping forward in theact of tilting the oscillating chute P to reject the same. Thestationary chute M is of pan form, and is permanently .attached to theuprights W by rivets or screws a a, and is obliquely directed forwardand downward toward a receiver, R,

placed to collect the accepted work, and is pro- 5 vided with notches Nin its opposite sides N', as shown in Fig. 2, to admit freely the pivotsIl of the connecting-rod G into place when the chute P is returned toits normal position, as shown in Fig. 1, in which position the twochutes P and M coalesce to form a long forward chute. The chute M, abovethe cuts N, terminates in rounded ears, which are perforated forbearings for the pivots S, upon which, as on a transverse axle, theoscillating chute P swin gs when operated by the trip mechanism. Thechute P is in form as shown, and is sufficientlyY narrow to lie in thetrough of chute M, and long enough to close the cuts N therein whenreturned, as shown in Fig. 1. The pivots S are located directly beneaththe rear side of the opening A in the machine-bench. The trip `mechanismconsists of the connecting-rod G,

pivoted at H to chute P, and at L to the operating-lever G', which ispivoted at P to the upright W, and the coiled spring K, which isfastened, at one end, V, either inthe floor, or in the cross-piecebetween the uprights W, and its loose end is extended to K', where it iscrooked to reach under the fore part of lever G', which it retracts,from position shown in Fig. 2 to position shown in Fig. 1. The sprin gis. added to quicken the return of the chute P to its normal position,which would be too slow if left to gravity alone, as' spikes are cut atthe rate of one hundred and twenty per minute 5 therefore, to reject adefective one, which can be known to be such by a skillful feeder, the

apparatus must be susceptible of instantaneous manipulation. The lever Gis manipulated by the foot of the operator, first, when he is Standing,by the pedal or cross-head L 5 second, when he iS seated on astool,bythe plunger D, connected to lever G at D, and guided and held upright byan enveloping clasp or sheath, E, arranged on the upright W5 as shown.

Depressing the fore end of the lever G', ei-

ther the plunger or pedal tilts the chute P to catch and reject aninitial cut or blank, Z, as.

shown in Fig. 2, which is, by this means, pitch ed into the receiver R'under the rear end of the machine, and the instant pressure is Withdrawnfrom the lever-pedal the spring K K' returns the chute P to receiveaccepted Work, as C, and conveys it to the receiver It placed under thefront part of the machine.

In the art of spike-making the practice has hitherto been to let theinitial and final cuts or ragged blanks, as Well as defective Work, passWith the perfect Work, and to be put upon the market unseparated. Myapparatus is, therefore, designed to eliminate these crudities from thisspecies of merchandise in a more convenient manner than can be done byunassisted hand-labor. Y

Having thus fully described my invention what I desire to secure byLetters Patent of the United States isi 1. The arrangement of thetransverse articulation of thepartsM P of the compound chute directlybeneath the forward end of the eXitopening leading from the dies of thespikemachine, substantially as and for the purpose herein shown anddescribed.

2. The trip mechanism composed of the connecting-rod G, theoperating-lever G', the coiled spring K K', or its equivalent, incombination With the oscillating chute P, these parts being arranged tooperate conjontly, substantially as and for the purpose set forth.

3. The combination of the chute P, connecting-rod G, lever G', plunger DD', and sheath E, or its equivalent, all constructed and arranged tooperate as and for the purpose herein set forth and described.

4. The oscillating chute P, in combination With the shield T, for thepurpose herein set forth.

In testimony that I claim the foregoing as my invention I have hereuntoset my hand this 13th day of September, 1873.

ALEXANDER MORRISON.
